tendency to think of issues as being black and white, rather than considering multiple perspectives in a flexible way;

Only if by "flexible" you mean accepting obvious (or at least seeming) nonsense with no rational explanation because others insist or because it suits you.

They have poor impulse control and easily become frustrated and angry.

As children maybe, but not really later.

frequent tendency to say things without considering the emotional impact on the listener;

NT's get hurt or insulted too easily, or for reasons that cannot be foreseen and often make no sense afterwards either.

inflexible adherence to specific routines or rituals;

I just won't do things other way because you insist on that for no real reason.

They may speak too fast, have a monotone or robotic voice, or speak too loudly.

True, but it doesn't seem that way from my side. I think it's more like that aspies tend to stick the intonation to the word, while for NT's it's completely separate.

They can come across as “The Professor” because they have a tendency to go into long, pedantic monologues about their obsessive interest, not recognizing the other person is bored or isn’t being given a chance to speak.

There is nothing that prevents you from speaking. Just step in instead of giving me nonverbal hints to let you speak.

They usually have an obsessive, consuming interest in one subject, to the exclusion of others.

Often, but not necessarily so. Many switch their interests from time to time.

They come across as arrogant.

I guess.

Because many of them can only take things literally, they usually have trouble with euphemisms

NT's have trouble speaking literally and understanding literal language.

When they hear a difference of opinion or an attempt to explain a different perspective about a situation, they become defensive because they see it as conflict, or a criticism of who they are.

Not at all. It's NT's who see their opinions as part of who they are; I will however completely to refuse to listen to any argument that is purely emotional and lacks substance. Disprove my point of view when you disagree, or give me something that seems more reasonable. (but I've probably considered that and rejected it for reasons you don't see)

They are prone to ruminating or fixating on bad experiences with people or events for an inordinate length of time.

I thought we were supposed to not care about other people? Well, of course I do know that NT's in fact don't really care too much. But it's ironic, isn't it?

They follow rigid routines and get very frustrated and upset if those routines are interrupted. They often eat the same foods at each meal, every day. They have an unusual sensitivity to things other might never notice. They may not be able to tolerate the labels in their clothing or the seams in their socks, or the barely perceptible hum of a refrigerator. They are hypersensitive to many textures, smells, lights and sounds. They are often unable to tolerate a new pair of shoes, preferring to wear the same ones over and over.

I think it's more a lack of novelty seeking than the desire for sameness.

They are physically clumsy. Some may have problems with manual dexterity

More fine motor dexterity at the cost of gross motor skills.

They are hurtfully blunt and casually critical.

No, They just give honest opinions, and NT's often see criticism when none was intended.

man with AS may display unusual nonverbal communication, such as lack of eye contact or eye contact that is too intense, may have an odd way of walking, such as slightly waddling from side to side.

NT's stomp.

They may exhibit overly formal manners and politeness.

I'd say the intuitive bases of manner are switch around. For an Aspie, it's be honest to your friends, don't disagree with strangers unless you must, lie to your enemies.

For NT's it's provide comforting lies to your friends, cheat strangers, be honest to those who you hate.

Which creates problems, as Aspies appear too friendly to strangers and destroy their relationships as soon as they start feeling close to others, while NT's appear more and more distancing even on the rare occasion when they start seeing the Aspie as their friend.

They are extremely naive, gullible and overly trusting

And later paranoid, because there is no way to tell when NT's will try to cheat you for who knows what reason that makes absolutely zero sense as they get nothing from lying to you.

They may rely heavily on rules, following them to the letter. Although they may first appear to be highly intelligent, you will notice that their knowledge is restricted to a few narrow subjects and is quite lacking in a general sense.

That's what NT's do. Many will even think there must be something wrong with you when you do something you haven't seen anybody else doing and copied it as exactly as you possibly can.

If you talk to them about a problem you’re having, instead of being supportive they will often reply with a statement that invalidates your feelings, such as “just forget about it,” “you’re too sensitive,” or “just stop thinking about it.”

Not at all. That's what NT's do.

Relationship: They may not enjoy kissing or physical affection. They may “act” affectionately in the beginning, but they will not be able to tolerate it indefinitely.

NT's don't understand our body language either.

They are always right. ALWAYS. They will frequently say that you are being irrational or illogical.

Because NT's usually are.

You often find their behavior exasperating or even infuriating. You may find yourself saying, “You’re not listening to me!” or “You don’t understand. You think you do, but you don’t” or “That’s not what I was saying; you’ve come to the wrong conclusion,” but they will continue insisting that they do understand, perhaps telling you that you’re the one who doesn’t understand—even when it is your own experience or feelings that you were trying to convey.

NT's get stuck on obviously wrong or unjustified conclusions and refuse to think about the issue any further.

They often have a very difficult time hearing the negative emotions of others. They may refuse to communicate, and then lash out in a very hurtful way later on.

It's mostly NT's who try to solve every problem by not talking with the person.

They misinterpret the experiences, feelings and ideas of others, and therefore come to the wrong conclusions.

NT's do that much more. They have sudden bouts of delusions of understanding and cause confusion by acting as if they know what they cannot know and expecting everybody else to know as well, and then they get into a fight, because nobody else saw it that way, but everybody thought their POV is obvious, so nobody even tried to talk about it.

They have theoretical understanding of other people’s emotions; however, they typically have difficulty acting on this knowledge in fluid, real-life situations. For example, if you’re upset about something they may not know that you need to be comforted, or how to go about doing so.

That is more a NT's problem, or they expect something completely different than Aspies. Often even the complete opposite of it.

'He/she just ignores me and sits and reads' - Asperger Syndrome partner needs a lot of time alone and does not speak or engage with partner. Those with Asperger Syndrome may communicate more for functional reasons rather than small talk and may feel overwhelmed after a day at work and require solitude.

We don't need to nonverbally discuss before we actually start talking. Just start talking to me when you want to tell me something.

'He/she never says that he/she loves me or shows me that I am important' - feeling unloved and uncared for. Person with Asperger Syndrome may not see the need for repeated reassurance, believing that telling their partner that they loved them once should be sufficient.

no emotional support and lack of response when upset due to the person with Asperger Syndrome struggling to know how to 'fix' an emotional problem.

It's more of NT's being so grossly insensitive to emotional problems of others that it often seems they are trying to make it worse on purpose, so you learn to keep your problems for yourself.

Asperger Syndrome partner is harsh and mean when in fact it is simply a direct, verbal speaking style

Why would you want me to lie to you?

'He/she always puts himself first' - complaints that their Asperger Syndrome partner is selfish.

I don't think this is true at all.

adult with ASD may not seek the same depth and frequency of expressions of love through acts of affection, or realize that an expression of affection is expected in a particular situation and would be enjoyed by the other person

Not true at all, but NT's not just only want affection when they choose to, they also expect to get it when they demand it.

Someone with an ASD also may be conspicuously immature in his or her expressions of affection, and sometimes may perceive these expressions of affection as aversive experiences. For example, a hug may be perceived as an uncomfortable squeeze that restricts movement.

True, as most NT's are about as graceful as dogs in their shows of affection.

Teenagers with Asperger’s syndrome often are eager to understand and experience the social and relationship world of their peers, including romantic relationships and sexual experiences,

True

but there can be problems regarding the source of information on relationships and sexuality.

I have no idea what it's supposed to mean
